BIOS archive for the Dell Latitude 5490 on Compal board LA-F401P, written in the name as laF401P. Compal's LA-xxxxP numbering identifies the motherboard, so verify the code on the PCB first. The image is intended for reprogramming the SPI flash with a hardware programmer when a board fails to post or is stuck after a bad update. Read and keep the original chip contents before writing, because the service tag and system data live in the factory dump.
